Inactive during diurnal hours, Scrub Nightjars roost directly on the ground (Robbins et al. 1994). The Scrub Nightjar is nocturnal and crepuscular, active primarily at dusk, dawn and night (Cleere 1998, Ridgely and Greenfield 2001b). The presence of a tapetum lucidum in the retina aid in crepuscular and nocturnal foraging on flying insects in open environments (Rojas et al. 2004).
The Scrub Nightjar is territorial (Cleere 1998).
Little information. A male was observed in aerial pursuit of a second individual (sex undetermined), making broad loops 10 m above the ground (Robbins et al. 1994); this may have been a courtship display (Cleere 1998).
Social and interspecific behavior
Specific species of various predators of the Scrub Nightjar have not been documented in literature.
